      1. clone and build wildfly
      2. start wildfly ./dist/target/wildfly-<version>/bin/standalone.sh
      3. configure wildfly-openssl via WF CLI:
        /core-service=management/security-realm=ApplicationRealm/server-identity=ssl:write-attribute(name=protocol,value=openssl.TLS)
        
      4. grab h2spec tool (uses GO lang) and execute:
        ./bin/h2spec -t -k -p 8443 -h 127.0.0.1
        or e.g.:
        ./bin/h2spec -t -k -p 8443 -h 127.0.0.1 http2/7
        to execute just some failing tests subset

    Description

      I can see bunch of NPEs and IllegalStateExceptions when I execute http2 testsuite against running Wildfly server (build from master/62583a78a850ba3fb182dda9b5ed35d99e016960 revision) running with JDK9 and wildfly-openssl (my openssl version is OpenSSL 1.1.0g-fips 2 Nov 2017):

      All exceptions seems to repeat. This causes 16 tests to fail. When I use JDK8 or when I switch back to JSSE ALPN instead of wildfly-openssl, no test fail at all and there are no NPEs in server.log anymore, although the IllegalStateExceptions still remains there.
